MicroStrategy, an American business intelligence company, would face a margin call situation if Bitcoin (BTC), which was the collateral used to take a loan from SilverGate Bank, falls to $21,000 or below, said the company’s chief financial officer Phone Le in its Q1 earnings call in March 2022. A margin call is received when the borrower needs to put additional money due to depreciation in the value of the mortgaged asset.
